How to convert string into 2-dimension array?

In order to convert string into 1-dimensional JavaScript array I could use 'eval()'. But how to convert string into 2-dimensional array?

My string is:

['stage 1', 1, 11, 111],['Stage 2', 2, 22, 222]

Execution "eval(...)" with such parameter creates a 1 array with 4 elements: ['stage', 1, 11, 111]. Instead I would like to have array of 2 elements, where each element in turn is another array of 4 elements.

I believe, I could split original string by ',' into list of substrings and call 'eval' for each of them and combine the result into a 2-dimensional array.

But I believe that more efficient way should already exist. Is there any? If yes, please advise.

Thank you very much in advance!

Instead of using eval it would be better to use JSON.parse:

var string = '["stage 1", 1, 11, 111],["Stage 2", 2, 22, 222]';
var array2d = JSON.parse("[" + string + "]");
console.log(array2d);
